Procedure of synthesis of sulfides containing a chloropropenyl fragment sensitive to bases was modified. The change in the sequence of reagents addition ensuring a contact of isothiouronium salt with a minimal base quantity and the application of a mixture hydrazine hydrate-alkali allowed the preparation of target sulfides under mild conditions in up to 93% yields.
Synthesis and Carbon-13 Nuclear Magnetic Resonance Spectroscopy of 5,6-Dihydro-2-methyl-1,4-oxathiin, trans-Tetrahydro-1,4-benzoxathiin, 1,4-Tetrahydro-benzoxathiin, the 4-Oxides, 4,4-Dioxides and Related Acyclic Compounds

The results of a 13C NMR spectral investigation involving 5,6-dihydro-1,4-oxathiins, 1,4-tetrahydrobenzoxathiin, trans-tetrahydro-1,4-benzoxathiin, and the corresponding sulfoxides and sulfones are reported.An interpretation involving a dipolar structure with (2p -> 2p)? conjugation as opposed to (2p -> 3d)? interactions with the vinyloxy sulfides seems consistent with trends in the 13C NMR shifts.For the sulfoxides and sulfones, the substituent-induced chemical shift (SCS) effects at the β vinylic carbons (βSO and βSO2 effects) are considerably less than those at sp3 carbons.The γSO and γSO2 values at the sp2γ carbons indicate deshielding, in contrast to the shielding at the sp3 carbons.
